The Paragon scanners incorporate three internal flame relays for customer BMS interface, eliminat- ing the need for a remote amplifier. Relay one signals the presence or absence of flame and responds to automatically set ON/OFF thresholds. Relay two signals internal faults as detected within the scanner by internal self diagnostics. Relay three signals flame temperature is above or below adjust- able user designated values. The flame and fault relay must be connected to the BMS to provide ade- quate safety monitoring of the flame presence. The temperature relay can be used for alarming or signaling or can be connected to the BMS for remote monitoring.

For accurate detection of flame presence, Paragon scanners monitor the amplitude of the modulation (the flame "flicker") that occurs within the targeted flame, over a wide frequency. During the scanner setup procedure, the amplitude of the target flame over time is automatically stored by the flame scanner, together with algorithms for optimum ON/OFF criteria. Fast Fourier Transform algorithms within the product determine and monitor the flicker frequencies of the flame and constantly com- pare stored and real time information. The combination of these multiple tests provides the perfect balance between reliable availability and operational safety.

Special features

This industrial flame detector performs like no other on the market. The paragon is an optical Pyrometer and flame scanner combined.

By monitoring flame temperature this scanner can give vital indications of thermal NOx formations before alarms are triggered by exhaust gas analysers.

This scanner can also aid in the even distribution of fuel to PF burners and help in commissioning over fired air / staged combustion systems.
